DATA COMMUNICATIONS AND NETWORKING
- Consider a metropolitan area with uniform user density, A mumber of base stations are deployed throughout this area forming a uniform layout. Assume that there are \(n\) users to be serviced in the coverage region of each base station, and that each user consumes one frequency channel
- In each cell. 5 channels are reserved for handoff purposes.
- The network operator considers two alternate designs: Design A and Design B. The cluster size in Design \(A\) is \(4,\) and the cluster size in Design \(B\) is 7 . The spectral efficiency in Design \(A\) is \(\rho_{A}-1\) bits/sec \(/ H z\), and that in Design \(B\) is \(\rho_{B}\) bits \(/ s c c / H z\)
- The total bandwidth that the network operator has is \(W \mathrm{~Hz}\).
For what value of \(\rho_{B}\) the two designs will provide the same rate (per user)?

In this question we will determine the maximum achievable transmission rate in the downlink of a wireless communication network. Here are the specifications of interest:- Base station (BS) transmit power. \(P_{t x}=200 \mathrm{~mW}\)- Transmitter (BS) anterma gain: \(G_{C X}=7 d B\)- Receiver (terminal) antenna gain: \(G_{\mathrm{rx}}=3 \mathrm{~dB}\)- Quality requirement: \(\mathrm{SNR}>5 \mathrm{~dB}\)- Carrier frequency: \(f=2 \mathrm{GHz}\)- Receiver noise figure: \(F=3.98=6 \mathrm{~dB}\)- Ambient temperature: \(T=290^{\circ} \mathrm{K}\)- Boltzmann constant: \(k=1.38 \times 10^{-23}\) joule \({ }^{\circ} K\)- Path loss: \(P L=\left(\frac{4 \pi}{\lambda}\right)^{2} d^{4}\)- Maximum...

A metropolitan area is to be given wireless digital telephone service. Throughout this area there is approximately uniform service demand. Assume that the frequency is allocated in two blocks of \(4 \mathrm{MHz}\) with a separation of \(50 \mathrm{MHz}\), one block for the uplink and the other for the downlink, which constitutes a frequency-division duplex (FDD) operation. The system uses the hybrid frequency-division time-division multiple access (FD/TDMA) schemes as follows: The frequency band is divided into \(500 \mathrm{kHz}\) "channels" (which is...

Title: Partners Health Care Systems (PHS): Transforming Health Care Services Delivery through Information Management According to government sources, U.S. expenditures on health care in 2009 reached nearly $2.4 trillion dollars ($2.7 trillion by the end of 2010).[1] Despite this vaunting national level of expenditure on medical treatment, death rates due to preventable errors in the delivery of health services rose to approximately 98,000 deaths in 2009.[2] To address the dual challenges of cost control and quality improvement, some have argued...
